Description

  The present invention relates to a method for stretching an agricultural biomat on a cocoon.

  Various agricultural multi-materials play a big role. Vinyl mulch is frequently used as one of such mulch materials.

  Depending on the raw material and its form, the vinyl mulch is for agricultural use, industrial use, civil engineering use, daily life use, etc., and most of them are vinyl chloride products.

  Recently, a sheet-like biodegradable plastic product that decomposes and disappears in soil as a multi-material has been developed.

  Agricultural mats are sheet-like mulch materials made from natural plant fibers, and are more water permeable and breathable than vinyl mulch.

  Agricultural biomats are made into a sheet by mixing various organic fertilizers (compost, humus, etc.), culture microorganisms, charcoal (bioreactor), etc., depending on the crop type.

  Vinyl mulch has a simple function of controlling weeds and increasing the soil temperature, and cannot be expected to have air permeability and water permeability. Therefore, vinyl mulch adversely affects crop growth and soil environment.

  In addition, vinyl mulch takes a lot of work to clean up after the crop is harvested, and in addition, environmental pollution due to dioxins generated by incineration is a major problem.

  Multi-material biodegradable plastic products have the disadvantage of insufficient water permeability and breathability.

  Agricultural mats take about 3 years to fully decompose and are suitable for preventing weeds of perennial crops such as tea, but not for annual crops.

  Conventional multi-materials are all formed in a sheet shape in advance, and spread the sheet-like multi-materials on the surface of the basket at the agricultural production site.

  An object of the present invention is to provide an agricultural biomat method for efficiently applying an agricultural biomat on the surface of a ridge.

  Examples of the solving means of the present invention are as follows.

  It is preferable that the material spraying means has a screw and a heater, and the material supplied from the material tank to the material spraying means is warmed by the heater and stirred with the screw, and then the material is sprayed on the surface of the bag.

  Immediately after the material is sprayed, it is preferable that the agricultural biomat and the cocoon stretched on the ridge are pressed together and shaped from above with a shaping tool.

  In order to improve working efficiency, it is preferable to arrange a compressor between the tractor and the rotary and to send high-pressure air from the compressor to the blowing means.

  Agricultural biomat materials are made by mixing various organic fertilizers (compost, mulch, etc.), culture microorganisms, charcoal (bioreactor), ash, sticky adhesive, etc., depending on the crop type. . Since ash contains a lot of calcium (lime), weeding effect can be expected. Examples of adhesives are funori, glucomannan, konjac, sweet potato and rice. Rice flour is easy to use and flexible, but it tends to be expensive. Glucomannan is advantageous in terms of cost. The agricultural biomat is preferably formed by pulverizing ash and / or compost, blending adhesives with them, and spraying them on the straw with air.

  Agricultural biomats are preferably set after being sprayed on the straw and then reacting with the moisture in the soil to harden and decompose after about 3 months.
